Amps for sale - MTX 81000D, Orion, MA Audio

So I bought a new car and this stuff isn't going in the new one so it has to go. Everything worked when it was pulled from the car but it hasn't been used in awhile. I pulled it from my old car and sat it on a shelf where it has been sitting for 3+ months. I'm guessing on prices here and I'm open to offers, just let me know.
